NSPredicate always gives back the same data
- by Stef Geelen
I am trying to work with NSPredicates. But it always give me back the same array. Here you can see my predicate.
NSFetchRequest *request = [[NSFetchRequest alloc] init];
NSPredicate *predicate = [NSPredicate predicateWithFormat:@"whichAlbum.album_id == %d", AlbumId];
[request setEntity:[NSEntityDescription entityForName:@"Picture" inManagedObjectContext:self.genkDatabase.managedObjectContext]];
[request setPredicate:predicate];
Also when I try it hardcoded. It gives back the same array.
NSPredicate *predicate = [NSPredicate predicateWithFormat:@"whichAlbum.album_id == 5"];
Here you can see my database model.
And here you can see how I put data in my database for entity Picture.
+ (Picture *)pictureWithGenkInfo:(NSDictionary *)genkInfo
inManagedObjectContext:(NSManagedObjectContext *)context
withAlbumId:(int)albumId
withPictureId:(int)pictureId;
{
Picture *picture = nil;
picture = [NSEntityDescription insertNewObjectForEntityForName:@"Picture"
inManagedObjectContext:context];
picture.url = [genkInfo objectForKey:PICTURES_URL];
picture.pic_album_id = [NSNumber numberWithInt:albumId];
picture.picture_id = [NSNumber numberWithInt:pictureId];
return picture;
}
Anybody can help me ?
Kind regards
